Study on Antimicrobial Activity to Wheat Leaf Blight-Causing Microbes
In this Test Example, antimicrobial activity of the inventive compounds to wheat leaf blight-causing microbe was determined and compared with that of the comparative compound (1).
Comparative Compound (1): (1RS,5SR)-5-(4-chlorobenzyl)-2-dimethyl-1-(1H-1,2,4-triazol-1-ylmethyl)cyclopentanol




An inventive compound was dissolved in dimethylsulfoxide 2 ml. The solution 0.6 ml was added to a PDA medium (potato-dextrose-agar medium) 60 ml at around 60° C. The mixture was mixed thoroughly in a 100 ml Erlenmeyer flask and poured into a petri-dish, allowing solidification of the mixture, to give a flat plate containing the inventive compound.
A flat plate containing a test microbe (wheat leaf blight-causing microbe) cultured separately was punched into pieces with a cork borer having a diameter of 4 mm and the circular plate obtained was placed on the flat plate media containing the chemical described above. The plates were cultured at 25° C. for 14 days after inoculation and the diameter of the microbial colony was determined. Hyphal expansion-inhibiting rate was calculated according to the following equation:

R=100(dc−dt)/dc 

(wherein, R: hyphal expansion-inhibiting rate (%), dc: diameter of microbial colony on non-treated flat plate, dt: diameter of microbial colony on chemically-treated flat plate).

The results thus obtained were evaluated into five grades according to the following criteria:
<Growth Inhibition>
5: hyphal expansion-inhibiting rate: 80% or more
4: hyphal expansion-inhibiting rate: 60% or more and less than 80%
3: hyphal expansion-inhibiting rate: 40% or more and less than 60%
2: hyphal expansion-inhibiting rate: 20% or more and less than 40%
